Make sure you are buying the exact same bios. Look at “Additional information” and compare it with your bios information. The fastest way how to do that is download SRB Polaris. In the gallery there is screenshot form SRB Polaris 3.2 of the bios. If you can’t find the exact same bios contact me via e-mail monerobiosedit@gmail.com and send your bios, I will add it.

Once you have some errors lower clocks a bit until there are no new errors. These clocks should be stable

After you find the best memory clocks you can set core clocks (overclock or underclock) then you can try lowering voltages.http://www.pcworld.com/article/250644/how_to_overclock_your_graphics_card.htmlHWinfo - find your GPU and the GPU memory errors line. Watch it for numbers. If there are any after few minutes your memory clock is too high. If you have few errors after hours it's no problem. But key is to have 0 errors. Memory errors can cause bad shares and may end up with BSOD

Some recommended clocks and voltages for RX cards - each card is different this is only for approx values!ETH

All of these bios have undervolted core and memory (VDDCI), but only a bit for stability with all cards, most of them also have memory OC. All bios use performance timings or Pro performance timings. You can find most of the performance timings in my Bitcointalk guide, those Pro performance timings have higher hashrate and they are not listed in my guide. You can get them only if you have my Premium pack, Pro peformance timings bios or in PBE 2.0.
